Description

Technical Field

[0001] This utility model relates to the field of jamming device technology, and in particular to a drone acoustic jamming device. Background Technology

[0002] With the rapid development and widespread application of drone technology, the need to counter illegal or dangerous drones in the aerospace environment is becoming increasingly prominent. Especially in areas such as military security, border control, protection of critical facilities, and security for large-scale events, effectively identifying, interfering with, and even controlling unauthorized drones has become a critical issue that urgently needs to be addressed. In recent years, significant progress has been made both domestically and internationally in drone countermeasures technology, mainly reflected in the integrated application of various methods such as signal jamming, navigation deception, physical interception, and laser strikes. Among these, signal jamming-based countermeasures equipment, due to its advantages of fast response speed, long range, and flexible deployment, has gradually become one of the mainstream technological approaches.

[0003] However, existing UAV countermeasures equipment still has many shortcomings and cannot meet the practical needs of complex airspace environments. Traditional jamming equipment has poor directionality and limited signal coverage, making it difficult to accurately locate target UAVs, resulting in low jamming efficiency. Secondly, most existing equipment is fixedly installed or manually adjustable, lacking flexible mechanical structure support and unable to quickly adapt to changes in dynamic targets. In addition, some equipment has poor vibration resistance due to unreasonable structural design, making it difficult to operate stably in complex environments, especially in high-speed UAV movement scenarios, where the equipment is susceptible to vibration and may fail.

A housing is fixedly connected to the outer side of the ultrasonic transmitter head, and a first elastic rope connects the housing and the ultrasonic power supply box. A second pulley is connected to the first pulley via a belt, and the housing is connected to the first mounting plates via a rotating shaft. The second pulley is fixedly connected to the rotating shaft.

[0005] The lower part of the outer shell and the ultrasonic power supply box is connected to a second elastic rope, and the upper part of the ultrasonic power supply box is fixedly connected to a first connecting post, and the upper part of the first connecting post is rotatably connected to a first sleeve.

[0006] A first gear is fixedly connected to the first sleeve, a second mounting plate is fixedly connected to the first sleeve, a DC motor is fixedly connected to the second mounting plate, and the output shaft of the DC motor is connected to a second gear, which meshes with the first gear.

[0007] The first connecting post is fixedly connected to an annular protrusion, and the inside of the first sleeve is provided with a groove that mates with it.

[0008] A dust cover is fixedly connected to the upper part of the first sleeve, and a drone mounting plate is welded to the upper part of the dust cover via a second connecting post.

[0009] The drone mounting plate is connected to a buffer connector, which includes a second sleeve. A connecting shaft is slidably connected inside the second sleeve. A shock-absorbing ball is installed at the lower part of the connecting shaft. A conical limit buckle is fixedly connected to the upper part of the connecting shaft, and a limit plate is fixedly connected to the lower part of the connecting shaft.

[0010] Compared with existing technologies, the advantages of this invention are as follows: By using a stepper motor to drive a pulley system, the ultrasonic transmitter head is rotated, enabling vertical angle adjustment and enhancing the device's ability to directionally track target drones. Combined with a DC motor and gear transmission system, the entire device can achieve dual adjustment of pitch and horizontal angles, expanding the coverage of interference signals and improving its combat response capabilities in complex airspace.

[0011] By employing a combination of stepper motors and DC motors, automatic adjustment to the direction of interference is achieved, overcoming the limitations of traditional equipment that relies on manual adjustment or fixed installation, and significantly improving the system's reaction speed and operational efficiency. The linkage mechanism between pulleys and shafts ensures coordinated movement among components, resulting in precise and rapid responses, adapting to changes in dynamic flight targets.
